RE46C102
CMOS Dual H-Bridge Driver
General Description
The RE46C102 is a dual H-bridge driver
with 35mA drive current and 16V V
BB
maximum driver supply voltage. A separate
low-side driver ground connection, Vss, is
provided for current monitoring of each
H-bridge driver. Each driver has two control
inputs:
ENABLE which enables the high-
side drivers and therefore connects
the driver supply to the motor
output. This input can be used for
pulse-width modulation.
PHASE which is used to reverse the
motor polarity.
All control inputs are CMOS and TTL
compatible and the logic section operates at
Vdd=5V.
